To alZ'w/zomitmay concern:

Be it known that I, CLARENCE R. Bon'rnin,

' a citizen of the United States, residing at. lilcKenzie, in the county of Carroll and 5 State of Tennessee, have invented a new and useful Plow, of which the following is a specification. I 1

The present invention *has reference to agricultural machines, and more particularly to a harvesting machine especially de signed for harvesting potatoes, beans, onions and the like agricultural products, the primary object of the invention beingto provide a machine of this type which will remove the potatoes or the like being harvested, from thesoil, and separate the earth and vines therefrom, at a single operation.

A further object of the invention is to provide means for agitating the screening member of the harvesting machine, whereby the earth and foreign matter may befreed from the vegetables as they pass to the rear of the machine.

With the foregoing and other objects in p View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction. hereinafter described and claimed, it being understood that. changes in the precise embodiment of eludes diverging beams 5 which have their forward ends connected as by means of the. bolts 6 passing through registering openings therein, the bolts 6 also providingmeans to secure the clevise 7 toth'e beams.

The beams 5 have their rear ends curved downwardly and forwardly as indicated at 8 where the same have connection with a relatively wide plow blade 9 of the shovei type, the width of the blade being such as to have its side edges extended beyond the side faces of the beams-5.

Secured to the upper edge of the plow blade 9 and disposed in spaced relation, are a the straps 10 which are bent around the supporting rod ll of the screening element. to

provide ahinge orbearing for the screening element, disconnection between the rod *1 and straps 10 being such as to permit of free vertical movement of the screening" element with respect thereto.

Thisscreening element also includes a rear bar 12 which has connection with the rod 11 as by means of the parallel space bars 13, the space between the bars beingsufficiently large to allow dirt and other foreign matter to fall therethrough. g I

Supported intermediate theside bars of the screening element is a hood 14: which .is in the form of a metal plate having flanges bolted to the central bars 13 of the screening element, and as shown this hood extends upwardly to guard the wheel 15 that operates thereunder. This wheel is mounted on the axle16 that is carried by the pivoted arms 17, pivotally connected with the slides 18, as at 19, the slides 18 being however carried by the blade 9.

Forming a part of the screeningelement are the side boards 20 which are curved outwardly to guard the screening element to prevent the vegetables from falling laterally I therefrom. Adjustable colters 21 are carried at the forward portion of the machine, each colter being supported by a bar22 which is provided with a reduced portion 23 movable through an opening formed in the head 24 of the vertically adjustable rod 25. These rods 25 are held in the socket members 26 by means of the set screws 27 thereby secur ing the colters in predetermined positions of adjustment. From the foregoing it will: -be seen'that these eolters cut the grassand weeds prior to the digging operation, thus" eliminating any possibility of the weeds and grass clogging the machine. I

In order that the machine may be guided I I whilein operation, handle bars 26 are provided and have connection with-the plow beam adjacent to the rear ends thereof.

In the operation of the device, the machine. 1 is placed at one end of a row of potatoes or the like to be dug, whereupon the machine is moved along the row, the blade-t of the machine removing the vegetables from the. The vegetables together with the.

earth. earth and weeds which adhere thereto, pass upwardly over the upper edge of the "plow, and onto the'screeningelement, which is being constantly vibrated by contact of the toothed Wheel 15 with the outer surface of the hood 14.

It Will'be seen that as the screening,

element is being vibrated, the earth and other foreign matter are dislodged from the vegetables and the vegetables are discharged at the rear of the screening element free of all foreign matter. ,7 5

Having thus described the invention, What is claimed as new is 1 A i harvesting plow comprising spaced beams having curved rear ends, a plow blade having connection With the curved rear ends of the beams, slides secured to the plow-blade and extending rearwardly therefrom, a pivoted screen ng member comprising a pluralityofspaced bars, a bar connecting the to each other, a Wheelsn'pported between the adjacent ends of the arms, said Wheel adapt ed to contact; With the hood to move the screening member vertically, and side boards carried by the screening member.

' In testimony that I claim theforegoing as my own, I have hereto aiiixed my signature in the 'presence of two Witnesses.
